Abstract

The instrument has an annular body (1) defining a bore (2). The hole (3) has two opposite rectilinear sides joined by semicircular arcs, and a groove all round it. The foot of a metallic ball (7) is forced into the hole with its axis (Y-Y') at right angles to that (X-X') of the bore. It carries two flats on opposite sides joined by ribbed semicylindrical portions. The ball is machined completely before the foot is driven into the hole with its ribs penetrating into the groove.

Description

Les instruments de musique à vent, notamment les clarinettes et les hautbois et instruments similaires, comprennent un corps définissant une perce. Sur la face latérale extérieure du corps sont fixées des boules de clétage entre lesquelles sont montées ultérieurement des charnières ou des clés.Wind musical instruments, including clarinets and oboes and the like, include a body defining a bore. On the external lateral face of the body are fixed locking balls between which hinges or keys are subsequently mounted.

Jusqu'ici une boule métallique était fixée dans le corps par un pied fileté qui était vissé dans un trou taraudé ménagé à l'avance dans le corps. Après que la boule avait été fixée au corps, on l'usinait malgré les difficultés d'accès des outils et machines dues à la présence du corps. Il n'était pas possible d'usiner la boule préalablement à sa fixation, bien que cela aurait été plus facile, parce que le vissage dans un corps en un matériau relativement tendre, notamment en bois, en matière plastique ou en aggloméré, ne permettait pas d'être sur que la boule ait toujours la même orientation, les alésages ménagés dans les boules pour le passage des clés et des charnières pouvant ne plus être alignés.Until now a metal ball was fixed in the body by a threaded foot which was screwed into a tapped hole made in advance in the body. After the ball had been fixed to the body, it was machined despite the difficulty of access to tools and machines due to the presence of the body. It was not possible to machine the ball before it was fixed, although this would have been easier, because screwing it into a body made of a relatively soft material, in particular wood, plastic or chipboard, did not allow not to be sure that the ball always has the same orientation, the bores made in the balls for the passage of keys and hinges may no longer be aligned.

L'invention pallie cet inconvénient par un instrument de musique, dans lequel il est possible d'effectuer un usinage complet-des boules avant le montage.The invention overcomes this drawback with a musical instrument, in which it is possible to carry out a complete machining of the balls before assembly.

Suivant l'invention, le pied a une section transversale non circulaire et le trou est délimité par un bord non circulaire conjugué.According to the invention, the foot has a non-circular cross section and the hole is delimited by a non-circular conjugate edge.

La section transversale comporte notamment, par exemple, une partie rectiligne ou deux parties rectilignes opposées et le trou est délimité par un bord rectiligne ou deux bords rectilignes opposés, encore qu'il soit possible de prévoir toute autre forme, et même de donner à la section transversale du pied la forme de deux arcs de cercles de rayons différents.The cross section includes in particular, for example, a rectilinear part or two opposite rectilinear parts and the hole is delimited by a rectilinear edge or two opposite rectilinear edges, although it is possible to provide any other shape, and even to give the cross section of the foot the shape of two arcs of circles of different radii.

En enfonçant le pied dans son trou correspondant, on est sûr que la boule conserve l'orientation souhaitée en raison des méplats, correspondant aux parties rectilignes de la section transversale, qui la guident.By pushing the foot into its corresponding hole, it is certain that the ball retains the desired orientation due to the flats, corresponding to the straight parts of the cross section, which guide it.

De préférence, le pied comporte une nervure perpendiculaire à l'axe de la boule et le trou comporte une rainure conjuguée de la nervure. Par axe de la boule on entend l'axe suivant laquelle elle est enfoncée dans le trou lors du montage. On maîtrise ainsi le niveau de la boule au dessus du corps.Preferably, the foot has a rib perpendicular to the axis of the ball and the hole has a conjugate groove in the rib. By axis of the ball we mean the axis along which it is pressed into the hole during assembly. We thus control the level of the ball above the body.

L'invention vise également un procédé de fabrication d'un instrument de musique à vent qui consiste à fixer une boule de clétage à un corps. Le procédé est caractérisé en ce que l'on usine complètement la boule avant de la monter.The invention also relates to a method of manufacturing a wind musical instrument which consists in fixing a keying ball to a body. The method is characterized in that the ball is completely machined before mounting it.

Au dessin annexé, donné uniquement à titre d'exemple, la figure 1 est une vue partiellement en coupe d'une demi clarinette,In the accompanying drawing, given solely by way of example, FIG. 1 is a partially sectional view of a half clarinet,

la figure 2 est une vue de dessous, suivant la flèche II de la figure 1, du pied de la boule.Figure 2 is a bottom view, along arrow II of Figure 1, the foot of the ball.

La figure 3 est une vue de dessus du trou, alors que le pied de la boule n'y est pas engagé.Figure 3 is a top view of the hole, while the foot of the ball is not engaged.

A la figure 1, la clarinette comporte un corps 1 sensiblement annulaire, d'axe X-X', délimitant une perce 2.In FIG. 1, the clarinet comprises a body 1 substantially annular, of axis XX ′, delimiting a bore 2.

Dans le corps 1 est ménagé un trou 3 qui, comme le montre la figure 3, comporte en section transversale deux parties 4 rectilignes opposées, reliées entre elles par deux arcs de cercle 5. Une rainure 6 est ménagée tout autour du trou.In the body 1 is formed a hole 3 which, as shown in FIG. 3, has in cross section two opposite rectilinear parts 4, interconnected by two arcs of a circle 5. A groove 6 is formed all around the hole.

Dans le trou 3 est enfoncé à force un pied d'une boule 7 d'axe Y-Y'. Ce pied comporte comme on le voit à la figure 2, deux méplats 8 opposés reliés entre eux par deux parties cylindriques 9 sur lesquelles sont ménagées des nervures 10.In the hole 3 is forced down one foot of a ball 7 of axis Y-Y '. This foot comprises, as can be seen in FIG. 2, two opposite flats 8 interconnected by two cylindrical parts 9 on which ribs 10 are formed.

Pour fabriquer la clarinette, on usine d'abord complètement la boule 7, puis on enfonce le pied 3 dans le trou, en sorte que les méplats 8,8 viennent en regard des parties rectilignes 4 et que les nervures 10 pénètrent dans la rainure 6 pour maintenir la boule enfoncée et ainsi empêcher un désassemblage involontaire.To manufacture the clarinet, the ball 7 is first completely machined, then the foot 3 is pushed into the hole, so that the flats 8,8 come opposite the straight parts 4 and the ribs 10 penetrate into the groove 6 to keep the ball pressed and thus prevent an involuntary disassembly.
